A ZDNet blog demonstrates three different ways to measure and/or adjust the operating temperature of a MacBook Pro—a topic that has caused considerable concern in recent months.

Lobotomo Software's Fan Control is a system preference that allows you to set an upper and lower temperature threshold for your MacBook Pro. The software then dynamically adjusts the fan speeds to keep your MBP within the temperature range that you define.

Macworld recently posted a similar story, though this was more focused on whether new MacBook Pro Core 2 Duo models run any cooler than their predecessors. Verdict: Not much. But if you're concerned at all about your MacBook's temperature, one of the utilities mentioned in the ZDNet story may help. — Rick Broida
